如何在kotlin中放大google地图中的某个位置？

implementation 'com.google.android.gms:play-services-maps:17.0.1'

<com.google.android.gms.maps.MapView
    android:id="@+id/mapView"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

class MainActivity : AppCompatActivity(), OnMapReadyCallback {
    private lateinit var mapView: MapView
    private lateinit var googleMap: GoogleMap

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        mapView = findViewById(R.id.mapView)
        mapView.onCreate(savedInstanceState)
        mapView.getMapAsync(this)
    }

    override fun onMapReady(map: GoogleMap) {
        googleMap = map
        // 在这里进行地图相关的操作
    }

    override fun onResume() {
        super.onResume()
        mapView.onResume()
    }

    override fun onPause() {
        super.onPause()
        mapView.onPause()
    }

    override fun onDestroy() {
        super.onDestroy()
        mapView.onDestroy()
    }

    override fun onSaveInstanceState(outState: Bundle) {
        super.onSaveInstanceState(outState)
        mapView.onSaveInstanceState(outState)
    }
}

override fun onMapReady(map: GoogleMap) {
    googleMap = map
    val location = LatLng(37.7749, -122.4194) // 指定位置的经纬度
    val zoomLevel = 15.0f // 放大级别，数值越大放大级别越高

    googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(location, zoomLevel))
}
